WILLIAM B. KIMBALL, OF PETERBOROUGH, NEW HAMPSHIRE.

IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent No. 43,314, dated June 28,1864.

T0 all whom it may concern,.-

Be it known that'I, W. B. KIMBALL, of Peterborough, in the county ofHillsborough and State of New Hampshire, have invented a new andImproved Stove; and I do hereby declare that the following is a full,clear, and

exact description thereof, which will enable any person skilled in theart topmake and use the same, reference being had to the accompanyingdrawings, making a partof this speciiication, in which Figure 1 is afront view ot' a stove, partly in section, constructed according to myinvention; Fig. 2, a horizontal section ofthe same, taken in the line mfr, Fig. l. Fig. 3 is a vertical section of the lower part of the stove,illustrating the manner of constructing the lower part of the frame, sothat the stone panels may be exposed to uniform heat.

Similar letters of reference indicate correspending parts in the severaliigures.

This invention consists in constructing the stove with an iron or metal:t'rameV filled in or provided with stone panels, the lower parts orbars ofthe said metal frame being made ot' such width as to elevate thestone panels above any accumulation of ashes in the bottom of the stove,and thus prevent suchunequal heating of different parts ot' the stonepanels as wou' d cndan ger their breakage. The i'ront ot' the stove isprovided with sliding doors, also constructed ot' iron frames filled' inwith stone.

The invention is designed for a cmbined open and close stove, and toburn either wood or coal.

A represents the baselplate ofthe stove, constructed of cast-iron, andprovided with feet a. To this base-plate the framing of the body or mainportion of the stove is secured. This framing is what may be termed askeleton--one composed of uprights b, connected at their upper and lowerends by horizontal pieces o. 'Ihe framing is also of cast-iron, and itmay be oi' any desired form, and it is secured together and to thebase-plate A by means of bolts, d. Ot whatever form this skeletonframing may be constructed, it is essential that large open spaces beallowed to receive stone slabs, B, to comprise by far the largestportion of the body of the stove. The nprights b, as well as thehorizontal pieces c of the framing, are so formed as to admit of thesides and top and bottom ot the stone slabs being fitted and secured inthem with close joints.

The stove has a lining, C, within it of stone slabs, and the front ofthe stove is provided with sliding doors D D, the upper and lower edgesof which are fitted and work in grooves e e.

The doors D D are constructed of cast-iron frames, tilled in or providedwith stone slabs I do n ot confine myself to any particular manner ofsecuring the stoneslabs in the castiron framing, for various plans mightbe devised for that purpose and all answer equally well. It is designed,however, to have the parts so arranged that the stone slabs may bereadily fitted in the framing, and secured iirni ly in position with butlittle labor and trouble.

The stove thus constructed of a castiron framing and stone panels willpresent not only an ornamental or chasteappearance, but will give out amore agreeable heat than those constructed exclusively of cast-iron, andthe stone slabs will also absorb the heat and radiate it into theapartments, so that the latter will be more uniformly heated than usualduring variations in the intensity of the iire.

I am aware that it is not new to construct the walls of stoves of stonepanels set in metal frames; but in stoves of this kind as commonlyconstructed the stone panels usually extend downward so near the bottomof the stove that their lower ends, being protected by ashes from theintense heat of the tire, are liable to crack by reason ot' theexcessive heating and expansion ot' the center part. To obviate thisdifficulty I construct the lower part, c', of the metallic frame, or thecorresponding ilange, A', ofthe base-plate, ot' such width that allparts of each stone panel will be subjected to nearly uniform heat, anddanger ot' breakage will thus be avoided.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

A stove composed of soapstone panels set in metal trames and recessed atbottom, as herein described, to receive the ashes and cause the loweredges of the stone to be eX- posed to as intense heat as the centerpart.
